How Many Litres of Water Does an Office Need per Person per Week?

Keeping your team hydrated is one of the simplest ways to boost wellbeing and productivity at work. But when it comes to ordering water for your office, it can be tricky to know how much is actually needed. Too little, and you’ll run out midweek. Too much, and bottles sit unused.

Here’s a quick, practical guide to help you work out how many litres of water your office needs per person per week, plus a few smart ordering tips from our delivery team.

πŸ’§ How Much Water Does One Person Need a Day?

According to the NHS, adults should drink around 6–8 glasses of fluids a day β€” roughly 1.5 to 2 litres.
At work, most people get about half of their daily hydration there, especially during office hours.

That means the average person drinks about 1 litre of water per working day, or roughly:
➑️ 5 litres per person per week (based on a standard 5-day working week).

πŸ’‘ Tip: Always round up slightly to allow for visitors, meetings, and warmer weather β€” hydration needs rise in summer or in air-conditioned offices.

Factors That Affect Water Usage

Every workplace is different, so it’s best to consider a few key factors:

  • Work environment: Offices with physical activity (e.g. warehouses or studios) use more water than desk-based teams.
  • Season: Expect a 20–30% increase in summer.
  • Office size and culture: Teams that encourage healthy habits and regular breaks tend to drink more water.
  • Meetings and guests: Client visits, training sessions, or events add extra consumption.
  • Events & catering: Keep a few smaller bottles handy for conferences, away days, or special occasions.
